Abstract

A modular concept for Silicon Carbide power devices is disclosed where a low voltage module (LVM) is designed separately from a high voltage module (HVM). The LVM having a repeating structure in at least a first direction, the repeating structure repeats with a regular distance in at least the first direction, the HVM comprising a buried grid with a repeating structure in at least a second direction, the repeating structure repeats with a regular distance in at least the second direction, along any possible defined direction. Advantages include faster easier design and manufacture at a lower cost.
